Abstract: A step generator for producing steps having constant edge parameters while driving varying loads includes a pair of DC coupled low speed diode switches (Q1, Q2) for slowly switching the output load current. A pair of capacitors (C1, C2) provide an AC coupled high speed input for rapidly, but temporarily, switching the output load current until the sustaining action of the low speed diode switch has occurred. A pair of resistor divided circuits (R1, R7 and R2, R8) in each of the low speed diode switches maintains a relatively constant reverse bias voltage across the diodes coupled to the capacitors. The high speed switching threshold is maintained at a relatively constant level which produces an output voltage step with constant edge parameters and no overshoot.

Abstract: A process is disclosed for improving the productivity of a supported polymerisation catalyst formed from a magnesium alkoxide which normally undergoes poor metathesis towards production of a magnesium halide support. The process comprises reacting the magnesium alkoxide with an alkoxysilane to form a different magnesium alkoxide which undergoes good metathesis at a temperature at or above the temperature at which the alcohol which is formed dissociates from the alkoxide. The resulting magnesium alkoxide is then subjected to metathesis to provide a supported polymerisation catalyst component for use in the polymerisation of olefins.

Abstract: The present invention operates by verifying correct latch operation in a digital circuit. After a value has been stored in a latch, electronic circuitry can verify that the value has been stored correctly. The electronic circuitry that performs this verification can be tested to insure that it is operating properly. Several latches can be wired into a scan chain and tested with relative ease. Operation of the present invention is illustrated by an enhanced master-slave latch system. In this system, two comparators are used. A first comparator (308) is used to determine if the internal state of the master latch is identical to the signal which had been applied to this latch's data input terminal (Q₁). A second comparator (310) is used to determine if the state transfer between the master (305) and slave (306) latches occurs properly. Each comparator consists of an EXCLUSVIE-OR function. By placing known logic levels on each input terminal of the comparison circuitry, the output terminal of the comparison circuitry can be examined for an expected logic level to verify that it is operating properly. By placing several latches into a scan chain (719) , a single latch can be loaded with data which will cause an expected signal to appear on the output terminal of this latch's comparison circuitry. This allows for simplified testing of a multiple latch system.

Abstract: A method for performing signal quality analysis on digital signals uses simultaneous dual threshold data acquisition. Using this method, the data need not be repetitive and, because the reference data and the variable data are acquired simultaneously, the logic analyzer continues to trigger and further measurements can be made after significant noise has been encountered. One threshold is designated the reference threshold and used to perform triggering and acquisition of reference data, while the other threshold is designated the variable threshold and used to acquire data for the noise margin analysis. At each increment of variable level, the data acquired by the reference acquisition and the data acquired using the variable threshold level is compared to see at what point in time and on what signal lines noise begins to affect the quality of the data. These data comparisons should be tolerant of minor timing variations that arise from the interaction of normal rise and fall times and the varying threshold level, and yet be sensitive to more significant changes in the data that arise from the effects of noise, marginal signal width or amplitude, or excessive rise and fall times.
